Description
DURAN® test tube with straight rim is a thick-walled laboratory vessel made of borosilicate glass 3.3, measuring 25 × 200 mm with a nominal volume of 70 ml. It is intended for converting substances and liquids into other states of aggregation and initiating further reactions in daily laboratory work. Reaction controls, test series and preliminary samples are typically performed in such tubes because only small substance quantities are required. The tube features a round bottom and a permanently fired white print for lasting identification. Its thick-walled construction provides particularly high mechanical resistance. Available with a straight rim, the design supports reliable handling during heating of small amounts, preliminary testing, as well as storage and transport of small liquid volumes. These durable glass tubes from manufacturer Duran/DWK Life Sciences are supplied in packs of 50 pieces and suit a wide range of routine analytical and preparative tasks where robust, reusable glassware is essential.
This article is part of Test tubes, in Tubes & vials.

Questions about DURAN® Test Tube, with straight rim
What is this article?
DURAN® Test Tube, with straight rim is the article on this page. Luminix Health distributes DWK Life Sciences for laboratory use. It sits in Test tubes, inside Tubes & vials, in Labware.
A test tube is the open cylindrical vessel for a small liquid, in borosilicate glass or in plastic. Rimmed and rimless mouths differ. The size is diameter by length. It is not graduated for a result, and a glass tube that will be centrifuged has a force limit.
A tube holds a small sample upright. A test tube is the open glass or plastic cylinder. A centrifuge tube is conical so a pellet forms at the tip, and it is rated for a centrifugal force the rotor will actually reach. A vial is a small closed bottle, often for a sample that will sit in an instrument. NMR tubes are a special case: the glass has to be uniform or the spectrum is the tube, not the sample. Laboratory ware is listed under ISO laboratory glassware.
